Application ined December 2o, 192s, serizl no. 681,711.

This invention relates to acombination lime hydrator and mortar makingdevlce and has special reference .to themaking of complete dry mortarsuch as used forplastering or the like. Y

The principal object of the invention isl to provide a simple andcompact machine for the production of a `finished dry mortar productfrom vhydrated lime, the same being accomplished simultaneously withthe'hyl dration of the lime.

Another object of the invention is the` provision of means wherebyeither hydrated lime or dry mortar may be made with the machine, or thelatter product accomplished by the machine without simultaneous hydration of the lime as desired.

@ther objects and advantages of the invention will appear in the furtherdescription thereof.

Referring now to the accompanying drawings forming part of thisapplication:

igure 1 is a side elevation of the-upper half of the machine, partlybroken, away, showing the lime hydrating apparatus and the hopper inwhich the ,other materials are added when the machine is used in themanufacture of mortar; and

Figure 2 is a similar view of the lower part of the machine, showing theconveyors,

dii

cooler, elevators, etc.

Referring particularly to Figure 1 of the drawings the stack of thehydrator is shown at 1, and the weighing and charging apparatus at 2,through which the material is weighed and fed to the hydrator or primarymixer. A water supply is also provided in any well lmown manner, it notbeing considered necessary to illustrate the same here, as this form oflime hydrator is old in the art.

IThe mixer proper is illustrated at 3, vfor the interior construction ofwhich and the arrangement of stirring devices thereof, reference is hadto myv former United States Patent No. 1,398,238 of November 29th, 1921;all the objects and advantages of which are derived in theinvention. Asuitable driving mechanism is provided such as illustrated at 4 forrotating the mixer, and the operation and control of the interior mixingdevices may be readily elected by the control mechanism illustrated at5.

e mixer 3 is mounted upon the rollerA bearing base 6 supportedupon asuitable `I have shown the hopper 18 supported by fabricated ysteelbasev or bed 7 `which rest upon a floor 8.

Concentrically below the base 6 and below the floor is the hopper or bin9, the same being provided at its lower end with a suitable feedingdevice 10, the' office of which is to feed the material being mixed tothe cooling drum 11 in the proper quantities; the base of the feedingdevice being of course connected in any suitable manner to the upper endof the cooling and mixing drum. This drum is provided with a cen-fl trallongitudinal shaft 12 the lsame having securely xed'thereto a ynumber ofpaddles or mixing blades 13, they being for the pur,- pose of furthermixing and a itatin the material as it slowly passes t rou the cooler,and the-shaft 12 is provided lwith any desired means for rotation, forexample the pulley and gear connection indicated 15 which leads througha pulverizer and air separator, of any suitable type, such as indicatedat 16, and the other end of the conveyor 15 communicates with a bucketelevator 17, which may lead to a baggin machine, or bins for storing ofthe materia To provide for the ,manufacture of mortar,

the floor 8 in which the desired additional material such as hair andthe like are placed.

In 'the lower end of the hopper is installed any form of agitator 19through which the material must pass to the feeder 20, the same beingdirectly connected to said hopper.

The feeder 20 is for the purpose of regulating the amount-of materialspassing therethrough in the right proportion with the amount of hydratedlime passing through the feeder 10. The feeder 20 communicates with oneend of the spiral conveyor 21 which v conducts the materialstherethrough and empties them into the upper end of i the cooling drum11 where th'e the lime hydrate and together pass through the cooler intothe second conveyor 15 and to the bucket elevator 17, from thence to theplace ofstorage.

'7s at 14. The material then passes from the lcooler 11 into one end ofthe'spvlral conveyor" are mixed with 10o The conveyor 15, as abovedescribed, also` communicates with the pulverizer and separator 16,said, communication being controlled by the slidel indicated at 22, sothat when mortar is being made, the slide may be closed, thus forcingall of the material through the conveyor l5 to the bucket elevator l?but when h dreteol lime only 4ie being reduced the sli e @muy he opened,

thus a lowing the hydrate to drop into the aired.

lt is Well lrnown inthe ort that other material such as cement issometimes incorpointed Within mortar and in which event it is obviousthat the some may be supplied to the hopper 18 with the heir und in anydesired quantities so that it, together with the hoirbecome thoroughlymixed during the travel ofthe conveyor 21 and then more thoroughlyincorporated in the min ne it continues through the machine.

meneur lln the production of hydrated le only the conveyor Qi'may heshut oh', es no material would pass therethrough, and the regularprocess or hydration and air seperattion take place as previouslydescribed.

Having thus described my invention, what l claim and desire to secure byLetters Patent, is:

The combination with a, lime hydretor, ont ineens directly associatedtherewith whereby either hnished ldry mortar or dry' hydrated lime maybe continuously supplied from seid means, and a, pulverizerintermedia-te of the mortar und hydrator discharges.
